Narrative:

We had the aircraft deiced and anti-iced at the gate with engines off and APU running. It was snowing at the time. After an uneventful taxi out and run up of the engines; we departed. The takeoff profile was uneventful until a couple hundred feet off the ground. I noticed a burning smell coming from the vents. The captain called out this burning smell as well and mentioned it smelled like burning deice/anti-ice fluid. After a couple more hundred feet in our climb; the cockpit quickly filled with white smoke. The flight attendant also called us via the emergency button. She notified me that the cabin was quickly filling with smoke as well. We turned off the packs as the obvious corrective action to stop the smoke. After doing this; the smoke began clearing and we finished our take off profile. At 4000 ft; the captain transferred the controls to me. I coordinated with approach to return to the field; create time to run checklists; and set up for the approach. The captain ran the QRH procedure; talked to the flight attendant; and briefed the passengers. At this time; the smoke had completely dissipated and we returned to normal procedures. The captain briefed the approach and then I transferred the controls back to him to fly the approach. The approach and landing were uneventful. Emergency vehicles did an exterior inspection of the aircraft after clearing the runway and then followed us back to the gate. Deice/anti-ice sprayed too closely to the APU inlet.maybe reminding the iceman to avoid the APU inlet especially when we are at the gate and deicing/anti-icing with the engines off.
